Note: See
TracTickets for help on using
tickets.
According to https://en.wikipedia.org/wiki/Szeged_index, this index is defined for connected graphs only.
I added a test and a doctest, a link to the wikipedia page for easier access to definition, and took the opportunity to do PEP8 cleaning of this method.
New commits:
